Bitcoin is known for its volatile price dips, so I certainly wouldn't be surprised. Also, Masterluc predicts a retest of the $10k area, and his track record speaks for itself. Whether that price target comes before or after new all-time highs is an open question, though. Sentiment is also hyper-bullish. I have noticed that top calls in my Twitter feed are virtually non-existent anymore. It's during these times when everyone is bullish that a big shakeout often happens because everyone is long.

That said, I wouldn't short this beast. The uptrend is incredibly strong. Any drop is a buying opportunity, not a shorting opportunity.
